N'-[(1E)-1-(4-Methoxyphenyl)ethylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide CAS 478076-92-5

Description

Compared with other compounds in its class, the molecular weight of 339.41 g/mol gives N'-[(1E)-1-(4-Methoxyphenyl)ethylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N'-[(1E)-1-(4-Methoxyphenyl)ethylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (CAS 478076-92-5), a certified reference material (molecular formula C18H17N3O2S, MW 339.41 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N'-[(1E)-1-(4-Methoxyphenyl)ethylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 339.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
